Welshpool - Haven Court (CSO)
Storm overflow run by Hafren Dyfrdwy.
"Not discharging" means the company's monitor reports no discharge right now — not that the water is clean. The feed publishes status only; no discharge volume is measured.
Year by year
Hafren Dyfrdwy's annual Event Duration Monitoring return to Natural Resources Wales (12/24-hour spill count), as compiled by The Rivers Trust.
"No data" means the monitor was not working or not required to report that year — not zero.
Discharges we have recorded
4 discharge periods since 20 Sep 2025. 4 of them come from Hafren Dyfrdwy's own event-duration-monitoring records (published by the company, Sep 2025 – Dec 2025); this overflow has no live feed, so nothing after that log is held. The official annual count is the figure to quote.

The year figures above use the EA's 12/24-hour counting method, so they are comparable with the official figures.

Nearest live rain gauge: Welshpool Raingauge, 0.7 km away. Brown shading = when this overflow was discharging; ▼ = a discharge start.
Overflow shading is a timing match, not proof of cause — heavy rain and spills share a trigger. Times come from the water company’s event-duration monitor (site status only; no discharge volume is published).
